Care access and life expectancy are shown for context, not graded.
From 2016 to 2025, 82 residents of Four died, against 95 expected from France’s death rates at each age: 14% fewer. The adjustment lowers most towns’ figures, so the comparison is what counts: the median of compared French towns is 12% below expected. The care-home adjustment is a TownRatings modeling step, not an official statistic. A less sure grade: it could be anywhere from C− to A.
